Add XE_BO_FLAG_NEEDS_1G to mark BOs that require 1G minimum page-size sizing. Update xe_bo_init_locked() to honor the new flag in the existing VRAM/stolen-memory minimum page-size sizing path. When XE_BO_FLAG_NEEDS_1G is set, the BO size is rounded up to 1G. Otherwise, the existing 2M and 64K sizing behavior is preserved. If multiple minimum page-size flags are set, the largest requirement takes precedence: 1G over 2M over 64K. v3 - commit message reworded Signed-off-by: Nareshkumar Gollakoti <[email protected]> Reviewed-by: Himal Prasad Ghimiray <[email protected]> --- drivers/gpu/drm/xe/xe_bo.c | 12 ++++++++++-- drivers/gpu/drm/xe/xe_bo.h | 1 + 2 files changed, 11 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/xe/xe_bo.c b/drivers/gpu/drm/xe/xe_bo.c index b1fdc802d27b..1c0b34c2c4ac 100644 --- a/drivers/gpu/drm/xe/xe_bo.c +++ b/drivers/gpu/drm/xe/xe_bo.c @@ -2352,8 +2352,16 @@ struct xe_bo *xe_bo_init_locked(struct xe_device *xe, struct xe_bo *bo, if (flags & (XE_BO_FLAG_VRAM_MASK | XE_BO_FLAG_STOLEN) && !(flags & XE_BO_FLAG_IGNORE_MIN_PAGE_SIZE) && ((xe->info.vram_flags & XE_VRAM_FLAGS_NEED64K) || - (flags & (XE_BO_FLAG_NEEDS_64K | XE_BO_FLAG_NEEDS_2M)))) { - size_t align = flags & XE_BO_FLAG_NEEDS_2M ?
